Bitcoin price predictions have been increasingly daring in recent months as Bitcoin breaks through one barrier after another - $1,200, $1,600, $1,800 and most recently $2,000.

In April, Blockchain CEO Peter Smith joined Snapchat investor Jeremy Liew in saying $500,000 would be the cost per coin by 2030. At the time, Bitcoin cost around $1,170 - around half its current price.

"We believe Bitcoin awareness, high liquidity, ease of transport and continued market outperformance as geopolitical risks mount will make Bitcoin a strong contender for investment at a consumer and investor level," the pair told Business Insider.

In the intervening month, market outperformance has been the topic on the lips of many.
